IMPROVEMENT IN SCHOOL-SEATS.

Specification forming part of Letters Patent No. lLQ, dated May 26, 1874application filed December 15, 1873.

ments. Fig. 2 is a central vertical cross ection. Fig. 3 is aperspective view of an ear projecting from the standard, andconstituting the female half of the seat-hinge. Fig. 4 is a perspectiveview, from the inner side, or one of the seat-supports, being the malehalt oi' the seathinge.

A A are standards, of any approved suitable pattern, secured together byties or rungs, and by the front, back, and bottom ci' thebook-receptacle B. About midway on `the front oi' the standards, ears u.project,

which are circular in form, and have an eye through their centers. Eachear is cast on the inner side of the standard, so as to leave a curvedrim, I), thereon, and a projection or stop, c, is formed at the upperend oi' said rim, clearly shown in Fig. 3. C C are castmeta-l arms,having lianges l d between, and onto one of which the boards forming theseat are secured. so that the seat may be shaped accordingly, and havecircular ends c to conform to the shape of the ears a, on which the)Yare fitted by the pins f entering the holes in said ears. These ends care made with a rim or flange, g, which rides on the outer edge of theears, and the edge of ends c works in the rim b. A lug, h, is formed onthe edge t' on a line with the pin'f,and has' a piece of rubber or othermaterial on it, the object of the lug be-` ing to abut against the stopo to hold the seat in' position for use, as in Fig. l, the rubber,

Sac., serving todeaden or prevent noise in lowering the seat. The end ofthe flange g abuts against a shoulder, la, on the ear, thus relievingthe lug h and stop c of undue pressure, and, consequently, strengtheningthe These arms are properly curved,

seat. Then not in use, the seat is simply turned up, as in Fig. 2. Thedesk-leaf D is composed ot castanetal arms E, having iianges i between,and onto which the board is secured. These arms are hinged to circularplates F on the ends of the standards. In these plates a slot, l, ismade, extending from their centers upwardly at about an angle offorty-tive degrees, and at the juncture ol the plates with thestandards; and on said standards two circular recessed ways, m n, aremade, on the inner one of which a stop, o, is formed. These devices formthe female portion or' the hinge,

whereby the desk-leai is secured to the standards. The male portion ison the ends G of the leaiarms E A pintle, p, in the center of said endiits in the slot l. A ilange, r, rides on the outer edge of the platesF, and a stop, s, abuts against the stop o, which, in connection withthe lower end oi' flange r, resting against the edge of the standard,holds the desleleail in position for use. The lug t rides on way fn, andserves to guide the movements of the leaf, while the edge n of end Grides in the way m to steady the same. A curved bar, H, is placedbetween the plates 011 which the leaf turns. A washer, w, is interposedbetween the plate and end to lessen friction. When the desk-leaf isdown, as in Fig. 2, and it is desired to use it, it is raised up untilthe stop .5^ comes in contact with stop o, when the pintle falls into anotch in the end of the slot I, and the end of flange r abuts againstthe standard edge, so that when ones hold thereon is released the leal'will be supported for use, as in Fig. l. To fold the leatl down again,it should be pulled up or raised, so as to free the pintle from thenotch in the slot, when the object can be readily accomplished.

What I claim. as my invention is- In a school-desk having a hinged seat,the

.arms C, provided with a tlange, g, pin f, and

stop lh, in combination with the ears a, recessed at b, and having thestops c and it, substantially as shown and described.
